Cabletron Systems 1800 Make sure the data bits and parity settings will match throughout the connection.

Configuring Async Ports 12-11
Initial Profile Name
is an async PA D profile (see page 12-2) that will be in e ffect on this port until the user
of the async device logs into the PAD, at which time the profile in the PAD Logins
record (see page 12-7) becomes effective. (If N is selected i n the Port record fo r Login
Required, the profile in the Port record is always in effect.) If the specified profile is
not defined in the database, the default profile, 90, will be in effect.
Login Required
determines whether or not async PAD users will be required to log in before con-
necting with this port. If Y, the user will be prompted to log in, and must enter a Login
ID and Login Password (see page 12-7) or an Abbreviated Address (see pa ge 12- 17 ).
Paritydetermines the type of parity checking that will be used on inc oming data. Pressing [K]
at the Port screen changes the value to the next one in the list:
0 = None 1 = Auto-detect 2 = Even 3 = Odd
The Smar tSwit c h 1800 sup port s 8 da ta bit s with no parity c hecki ng , or 7
data bits with even or odd parity checking. They also support 7 data bits
with auto-detect parity checking if X.3 Line Speed is set to Autob aud and
PAD profile 21 is configured to check parity.
Make sure the data bits and parity settings will match
throughout the connection.
DCE Cable Attac he d
identifies whether the port will act as a physical DCE (DCE Cable Attached = Y) or
DTE (DCE Cable Attached = N).
Mask Link Alarms
prevents (if enabled) transmission to the collecting node of the link alarms 400-406
(Link Enab led, Li nk Disa bl ed, et c.)
Genera te M -bit Packe ts
is used by the PAD to turn on the M-bit in the X.25 data packet if more than one packet
is required to transmit the data from the PAD.
Default Calling Address
will be inserted into an incoming X.29 Call Request if the packet does not contain a
calling address. This parameter is relevant only if Disable X.121 User Calls is N.
Disabl e X.1 21 Us er Ca lls
will (if Y) cause the port to accept only those calls that substitute an abbreviated
address (described later in this chapter) for the called address.
Autocall
causes (when enabled) the PAD to automatically call the remote device (Called
Address) when the link comes up, either through rebooting the node or pressing [F7]
after changing Autocall to Y.
